如何获取Nativescript-plugin SMART_BANNER高度

Question

Nativescript Firebase插件有Admob，您可以使用智能横幅，但我们不能检测横幅的高度。在不同屏幕大小上加载横幅后，我能得到谁的横幅高度？

  firebase.admob.showBanner({
    size: firebase.admob.AD_SIZE.SMART_BANNER, // see firebase.admob.AD_SIZE for all options
    margins: { // optional nr of device independent pixels from the top or bottom (don't set both)
      bottom: 10,
      top: -1
    },
    androidBannerId: "ca-app-pub-9517346003011652/7749101329",
    iosBannerId: "ca-app-pub-9517346003011652/3985369721",
    testing: true, // when not running in production set this to true, Google doesn't like it any other way
    iosTestDeviceIds: [ //Android automatically adds the connected device as test device with testing:true, iOS does not
        "45d77bf513dfabc2949ba053da83c0c7b7e87715", // Eddy's iPhone 6s
        "fee4cf319a242eab4701543e4c16db89c722731f"  // Eddy's iPad Pro
    ],
    keywords: ["keyword1", "keyword2"], // add keywords for ad targeting
    onOpened: () => console.log("Ad opened"),
    onClicked: () => console.log("Ad clicked"),
    onLeftApplication: () => console.log("Ad left application")
  }).then(
      function () {
        console.log("AdMob banner showing");
      },
      function (errorMessage) {
        dialogs.alert({
          title: "AdMob error",
          message: errorMessage,
          okButtonText: "Hmmkay"
        });
      }
  );

Answer 1

，我们先得到屏幕大小，然后用SMART_BANNER逻辑进行计算。

导入这个平台

const platform = require("platform") 

高度除以比例

const screenHeightDp =platform.screen.mainScreen.heightPixels / platform.screen.mainScreen.scale;

将计算作为智能横幅工作。

const BannerHeight = screenHeightDp > 720 ? 90 : screenHeightDp > 400 ? 50 : 32;

这是我们的旗帜高度

console.log(BannerHeight);
